[PATCH 10/10] mfd: wm831x-core: Supply description wm831x_reg_{un}lock args

[Lee Jones]

Kerneldoc syntax is used, but not complete.  Descriptions required.

Prevents warnings like:

 drivers/mfd/wm831x-core.c:119: warning: Function parameter or member 'wm831x' not described in 'wm831x_reg_lock'
 drivers/mfd/wm831x-core.c:145: warning: Function parameter or member 'wm831x' not described in 'wm831x_reg_unlock'
